Abstract

The first selenite carbonate Cd-3(SeO3)(CO3)(OH)(2)] has been hydrothermally synthesised and characterised by single-crystal X-ray diffraction and IR spectroscopy. It is built up from a network of edge- and vertex-sharing pyramidal [SeO3](2-) groups, trigonal [CO3](2-) groups, distorted CdO6 octahedra and distorted CdO8 square anti-prisms. The CdO6 groups form infinite 'buckled' sheets in the ac plane with the SeO3 and CO3 groups cross-linking the sheets. The CdO8 polyhedra are wedged between adjacent sheets, sharing edges with both the selenite and carbonate groups. Crystal data: Cd-3(SeO3)(CO3)(OH)(2), M-r = 558.19, orthorhombic, Pnma (No. 62). a = 6.5820(3) Angstrom, b = 10.4485(5) Angstrom, c 10.3999(5) Angstrom, V = 715.22(6) Angstrom(3), Z = 4, R(F) = 0.0216, wR(F-2) = 0.0525.
